I don't pretend to understand it but I still get the strong impression it could be very useful.

Certainly not exactly the same thing but still on the same subject of quantum computers;

Anneal seems to me the wrong word to describe that process talked about.
In my world, say, ion implanters, the first thing that happens is dopants get slammed into the surface of say, silicon wafers, with the ions buried at predetermined depths below the surface of the wafer. The problem with that from a semiconductor POV is that depth has a jumbled up mess of ions more like a plowed field when what you need is a crystal structure.
So annealing does its magic, when you heat the wafer up to around 1000 C for ten or 20 minutes, the crystal structure rebuilds itself but now including the conductor ions, either positive or negative conduction so you now have a kind of ionic way station of ions taking up the place of a silicon atom which allows conduction to happen.
So in our world, annealing is a high temperature effect leading to recrystallization which seems to me the total opposite to the near zero degree stuff going on in 'quantum annealing'.

Corporate America needs to figure out how to make huge profits from Quantum physics !! Then we will all benefit from the technology !!
